Cardiology - Cardiology

Cardiology is the study and treatment of disorders of the heart and the blood vessels. A person with heart disease or cardiovascular disease may be referred to a cardiologist.
Cardiology is a branch of internal medicine. A cardiologist is not the same as a cardiac surgeon. A cardiac surgeon opens the chest and performs heart surgery.

A cardiologist specializes in diagnosing and treating diseases of the cardiovascular system. The cardiologist will carry out tests, and they may some do procedures, such as heart catheterizations, angioplasty, or inserting a pacemaker.

If a person has symptoms of a heart condition, their physician may refer them to a cardiologist.
Symptoms that can indicate a heart problem include:

  • shortness of breath
  • dizziness
  • chest pains
  • changes in heart rate or rhythm
  • high blood pressure

A cardiologist can carry out tests for a heart murmur or an abnormal heart rhythm.
They often treat patients who have had a heart attack, heart failure, or other heart problems. They help make decisions about heart surgery, heart catheterization, and angioplasty and stenting.
